Vacuum tube

1. The hardware, or the physical parts of a computer, is one factor that has been constantly changing throughout the development of computers. Two elements of hardware in particular have progressed as generations go on: data transfer and storage. One challenge for computer engineers from the start was deciding how to transfer data through the computer. The first computer, the ENIAC, required 18,000 vacuum tubes to do so, and weighed about 20 tons. Because of its huge size, its power consumption was 150,000 watts (Piguet). Evidently, size and power consumption were major issues from the start. Vacuum tubes were a continuous source of difficulty due to expenses, and the fact that they were constantly burning out. Eventually, the invention of…

The history of computing technology can be organized into four distinct generations, each defined by a distinct transformation in technological innovation. The first generation stretched from 1947-1957, and is identifiable by its use of vacuum tube technology. This generation transitioned into the second generation during the late 1950’s with the use of transistors. Subsequently in the 1960’s the third generation began, classified by its use of integrated circuits. The fourth generation of…

and speed. The second and revolutionary idea was the idea of transistors. A Transistor is a device put inside of a computer or calculator that is used to amplify and switch electronic signals. This basically took a signal from the input device and sent it into the computer and to the output device. This may not seem like that big of a deal but the old technology was much larger, slower and used more energy. The first transistorized computer was in 1953 and completely changed the game. These…

Personal Electronic Devices are a blessing and a curse to society. Some people believe that Personal Electronic Devices will spell the downfall of humanity as we know it and while I don’t personally agree with that statement I can see where people would come to that conclusion from. Personal electronic devices are more addicted to people in today’s society than any other addiction in human history. No other time in history has there been one sole thing that near every human has and uses…

“Twenty two percent of teachers have access to the right level of technology in the classroom.” (PBS, 2011) In this research paper, I will look at technology and the effects on students and teachers; specifically, in a language arts classroom. The problem will be examined over time as technology has changed. In addition, how technology has been integrated into the classroom. There are many facets to technology use in the classroom. The first is how technology is use has changed over time.…

The Impact of Screen Time on Sleep As the Internet develops rapidly in today’s dynamic world, it is extremely hard to imagine how our lives would be without electronic devices. In 2014, an investigation from The National Sleep Foundation found that 89 percent of adults and 75 percent of children have at least one electronic device in their bedroom (Scutti). An child health survey in Australia conducted by the Royal Children’s Hospital Melbourne reveals that almost half of all children (43%) use…

In the article, Watching TV Makes You Smarter, Steven Johnson argues that many of the shows that our population considers unhealthy are actually relatively healthy for our brains. On the other hand, Dana Stevens argues in her essay, Thinking Outside The Idiot Box, that Steven Johnson’s thesis makes absolutely no sense and that television in no way gets our brains thinking or makes us smarter. Johnson starts by explaining what he calls the Sleeper Curve. He does this by comparing older TV shows…

Children and Media Devices Our media devices have become a valuable part of our everyday lives and the way we communicate; we get text messages for our dentist appointments and e-vites for birthday parties. Mostly this is viewed as a helpful and informative tool for staying in contact with friends and family or receiving news updates and for educational purposes. But, as with most things, there is a limit; how much is too much? My goal is to look specifically at children and the short and long…

Electronic devices are everywhere in world today, from internet of things to machine learning super computer to computer cars helping people communicate locally and globally with ease. People think of computers, cell phones and the Internet as the only sources for digital evidence, but any piece of technology that processes information can be used by criminals in a criminal intent. Investigators need to be able to recognize and properly seize potential digital evidence. Digital evidence is…

1. The media I use the most is television, while print is my least used form of media. This is what I had expected, since I rarely feel the desire to sit down and just read during the school year, I’d rather watch several television episodes. Relaxing on my bed or couch watching TV or Netflix sounds like a more enjoyable evening, instead of sitting at my desk reading boring textbooks for physics. Plus, I traveled home this weekend and all of my recorded shows were ready to be watched, since…
